Man pretended to be cop to score cheap doughnuts

A Florida man was so apparently desperate for a cheap sugar fix that he allegedly pretended to be a cop to score a police discount on doughnuts.

Charles Barry, 48, is accused of repeatedly flashing a phony badge at Dunkin' Donuts workers and claiming he worked as a United States Marshal.

Dunkin Donuts employee Michelle Hoeltk claims Barry was a regular customer who had been "abusing his [law enforcement] discount by coming in on the weekends with his family", which prompted store managers to stop offering him reduced prices.

On the morning of November 6 Barry returned to the store and demanded the discount, which was denied to him.

An employee said Barry then held up a firearm in its holster and said "See, I am a cop!"

Barry returned to the store the following day, when his vehicle's licence plate was recorded on a surveillance camera while he was in the drive-through.

On November 12, Barry was spotted by police as he again drove away from the Dunkin Donuts. An officer stopped him and "observed... a law enforcement badge in his pocket," according to the sheriff's report.

Barry admitted to his misdeeds and was arrested, police say.

"I did a stupid thing!" he reportedly confessed to the officer as he was booked.

An apologetic Barry was charged with impersonating a law enforcement officer.
